[0022] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.
[0023] Example 1:
[0024] As attached Figure 1 To the attached Figure 6 As shown:
[0025] The top of the paint spraying machine is provided with an adjusting screw 5, and the adjusting screw 5 is connected to the paint spraying machine by the adjusting screw 5. The adjusting screw 5 is connected to the paint spraying machine by the adjusting screw 5. The adjusting screw 5 is connected to the paint spraying machine by the adjusting screw 5. The control screw 5 is driven by the motor 4 to rotate, and the position of the adjustment slide 3 on the paint bracket 1 can be adjusted to meet the clamping operation of pipes of different lengths.
[0026] Among them, the three-jaw chuck 6 is symmetrically provided with two rotatably connected front side wall tops of the rear end of the paint bracket 1 and the top of the rear side wall of the adjustment slide 3. A connecting ring groove 601 is opened in the rotatably connected side wall of the three-jaw chuck 6 and rotatably connected to the connecting swivel 2. A meshing gear ring 602 is provided in the circular hole in the middle of the rear side wall of the three-jaw chuck 6 rotatably connected to the paint bracket 1. The top of the meshing gear ring 602 is meshed with the driving gear 401 at the front end of the driving shaft of the motor 4 installed on the top of the rear side wall of the paint bracket 1. The specific function is to cooperate with the motor 4 installed on the top of the rear side wall of the paint bracket 1 to drive the three-jaw chuck 6 to rotate when the driving gear 401 and the meshing gear ring 602 are engaged, thereby driving the fixed pipe to rotate through the three-jaw chuck 6, so that the paint surface can be more uniform when painting the pipe.
[0027] Among them, the sliding guide holes 701 on the left and right sides of the bottom of the paint slide 7 are slidably connected to the rectangular side walls on the left and right sides of the guide slide 101 opened on the paint bracket 1, and the sliding guide hole 701 in the middle of the paint slide 7 is slidably connected to the outside of the control screw 5 inside the guide slide 101. An extension plate 702 is fixedly installed at the bottom of the rear side wall of the paint slide 7, and a closed end block 703 is fixedly installed at the rear end of the extension plate 702 and the bottom of the front side of the paint slide 7. The top middle of the paint slide 7 A hexagonal limiting sliding hole 704 is provided, and the limiting sliding rod 9 is slidably connected to the limiting sliding hole 704. The top of the limiting sliding rod 9 is five millimeters larger in diameter than the bottom end. A paint tray 901 with a forty-five-degree deflection is fixedly installed at the bottom of the limiting sliding rod 9. A through paint hole is provided in the middle of the bottom of the paint tray 901. Two paint brushes 903 are symmetrically installed at the bottom of the paint tray 901. Two connecting columns 902 are symmetrically installed on the top of the paint tray 901. A support is sleeved on the connecting column 902. The spring 10 has a specific function. By passing the pipe through the paint slide 7, the paint plate 901 connected to the bottom of the limit slide 9 is tightly attached to the top of the outer wall of the pipe under the action of the supporting spring 10. When the pipe rotates, the air blowing ring 11 fixedly installed on the front side of the paint slide 7 blows high-pressure gas to the pipe, thereby blowing off the dirt attached to the outer wall of the pipe, so as to improve the cleanliness of the outer wall of the pipe during painting. The paint is distributed on the outer wall of the pipe through the paint holes opened in the paint plate 901. Then, as the pipe rotates, the paint brushes 903 on both sides of the paint holes at the bottom of the paint plate 901 evenly apply the paint on the outer wall of the pipe and increase the adhesion effect of the paint. The paint slide 7 is controlled by the electric cylinder 8 to realize the forward and backward sliding of the paint slide 7, so as to change the painting position in time. The extended receiving plate 702 at the bottom rear side of the paint slide 7 is used to receive the painted part of the pipe to prevent paint from dripping onto the device and causing the sliding problem of the paint slide 7.
[0028] The specific usage and function of this embodiment are as follows:
[0029] When the pipe uniform painting device is used, the same structure is adopted at the rear end front side wall of the painting bracket 1 and the rear side wall of the adjustment slide 3, and the connection with the three-jaw chuck 6 is realized with the cooperation of the connecting swivel 2, so that pipes of different diameters can be clamped and fixed by the three-jaw chuck 6, which is convenient for painting pipes of different diameters. The control screw 5 is driven to rotate by the motor 4 to adjust the position of the adjustment slide 3 on the painting bracket 1. The motor 4 installed on the top of the rear side wall of the painting bracket 1 cooperates with the driving gear 401, and the three-jaw chuck 6 is driven to rotate when the driving gear 401 is engaged with the meshing gear ring 602, thereby driving the fixing through the three-jaw chuck 6. The fixed pipe rotates, and then the pipe is passed through the paint slide 7, and the paint tray 901 connected to the bottom of the limiting slide 9 is tightly attached to the top of the outer wall of the pipe under the action of the supporting spring 10. As the pipe rotates, the blowing ring 11 fixedly installed on the front side of the paint slide 7 blows high-pressure gas to the pipe, thereby blowing off the dirt attached to the outer wall of the pipe, so as to improve the cleanliness of the outer wall of the pipe during painting, and the paint is distributed on the outer wall of the pipe through the paint holes opened in the paint tray 901, and then as the pipe rotates, the paint brushes 903 on both sides of the paint holes at the bottom of the paint tray 901 evenly apply the paint on the outer wall of the pipe and increase the adhesion effect of the paint.
[0030] Example 2:
[0031] By replacing the three-claw chuck 6 on the top of the adjusting slide 3 with a top of the adjusting slide 3 having an annular groove, the adjusting slide 3 can support the end of the pipeline, thereby further improving the convenience of disassembly and assembly of the pipeline.
